Introduction
The SARS-CoV-2 virus is the causative organism for Corona disease 1 . It causes respiratory distress, fever, cough, and sometimes gastrointestinal manifestations 2 . Although corona disease was evident for a longer period nowadays it became pandemic. The severity of features varies from mild to severe. As the teaching activities are affected all over the world, 3 online teachingsare becoming popular as an alternate method. Preventive measures are adopted by the government inthe education sector, for preventing person-to-person contact through online teaching 4 . As a result of the COVID 19' pandemic, the entire landscape of education is changed 5 . The notion of distance education and online learning has emerged as a necessity that raises questions about its usefulness.
This study compares the effectiveness of online versus traditional learning. When comparing the two, the most obvious difference is concerned with the perceived lack of human interaction, which is not possible.
The foremost method to translate this phrase would be no physical interaction for online learning, whereas classroom learning constitutesphysical interactions with the instructor and the student, online learning transits this element into the physical environment 6 . Physical education has a considerably greater in uence on a student's personality and cognitive abilities, allowing the student to better confront the teacher and get good test results.
The main goal of this study was to nd out the thoughts of our university students about online versus physical education, and how might we improve online teaching to achieve high academic results, if we have to live with the Covid-19 virus for a longer period.

Methods
This comparative cross-sectional study was conducted from December 2021 to January 2022at the anatomy department in collaboration with the physiology department LUMHS Jamshoro by nonprobability convenience sampling technique. Permission was taken from the ethical review committee of the Liaquat University of medical and health sciences Jamshoro.
During the Covid-19 epidemic, the research was carried out to observe how online versus physical instruction are comparable. The primary goal of this research was to improve online education by taking into account the challenges that our university students face in light of our available resources and determining the most effective teaching style from the perspective of our university students. As a result, the methodology used in this study was explanatory and correlational. The participants wereMBBS/BDS medical studentsof Liaquat University of medical and health sciences Jamshoro, and the sample size was a convenience sample of 246students. Students were recruited through a mobile app (i.e., WhatsApp), and the study lasted for two months. They were invited to complete an anonymous online survey using a Google Form, and all gave their informed consent.
Data were stored and analyzed using IBM-SPSS version 23.0. Counts with percentages were reported for the best teaching method voted by respondents, Advantages, and disadvantages of online and physical teaching methods were also assessed. Opinions were compared across the group using the Pearson Chi-Square test. P-values less than 0.05 were considered statistically signi cant. The pie diagram also reported for the vote of best teaching method.

Results
In the present study, there were two hundred forty-six samples surveyed among them 74.8% voted the physical teaching, 12.2% voted for online teaching and 6.5% elected both kinds of teaching methods, whereas 6.5% did not vote for any teaching method as the best teaching method. (As mentioned in Pie diagram-1).
Table-1 reports and compares the advantages of the online teaching method. For online teaching 86.7% said it is the best way to deliver lessons, 90% said online teaching has the number of tools as part of their lesson plans, 96.7% said online education allows students to attend classes from any location of their choice, 96.7% said online lectures can be recorded for further reference, 90% saidonline teaching is for more affordable as compared to physical learning, 76.7% said it improves students attendance, and 70% said it is a good wayto create a better learning environment. Among these statements, outcomes on an e cient way to deliver, affordability, attendance, and creation of perfect learning environment givea signi cant association with another kind of teaching methods (p<0.01).
Table-2 reports the disadvantages of the online teaching method. For online teaching 56.7% said the inability to focus on the screen for a longperiod, 66.7% said they are easily distracted by other sites, 73.3% said the bigger challenge of online classes is internet connectivity, 53.3% said they feel lonely, 90% said online classes required training of teachers and 50% said health hazard due to increase screen time.Statements on inability to focus, internet connectivity, sense of isolation, and health hazard givea signi cant association with another type of teaching method (p<0.05). Table-3 reports the advantages and disadvantages of physical teaching methods. For physical teaching all were agreed on physical education provides a healthy environment to students for learning, 97.3% said it builds the character of a child, 98.4% said students get the chance of interaction with their subject teacher,96.7% said they learn a lot from their peers, 99.5% said physical education clears the concepts of the students by interacting with their teachers, 97.3% said it motivates the students to attend their respective institutions, 95.1% said reward associated with physical education, 92.9% said it makes the carrier of the students, 97.3% said physical education provides a sense of competition among students, 58.2% said physical education taking too much of the students time, 54.3% said physical education is expensive as compared to online teaching. Pearson Chi-Square test is showing a signi cant association of all these statements with another kind of teaching method adopted by the respondents P<0.05.

Discussion
In the present study, there were two hundred forty-six samples surveyed among them 74.8% voted the physical teaching, 12.2% voted for online teaching and 6.5% elected both kinds of teaching method, whereas 6.5% did not vote for any teaching method as the best teaching method. Similar results were there in a local study by Abaid Ullah et al, they found that all the students were facing the same issues with online teaching, whether they were at the school level or university level 7 . Another similar study by Tej Bahadur Karki et al found that a higher number of students responded that physical class was more comfortable than the online class 8 .
A couple of unsimilar studies from Saudi Arabia concluded that the online teaching method was wellreceived, and all participants agreed that online sessions were time-saving and that their performance was improved due to the enhanced utility of time 9 . While in another study online learning was more convenient, as demonstrated by the fact that 28.5 and 31.9 % of the respondents thought that it was much more effective and somewhat more effective, respectively 10 . This difference of opinion is due tothe easy availability of electricity (no-load shedding), internet facility and laptops in their country.The results of an international study indicate that students react differently to online teaching methods, their reaction is based on their pro ciency in using online tools, their ability to technically access online courses, and the instructors' manner in conducting learning activities 11 .
Among samples who voted for online teaching most said it is a better method of teaching, has several tools as part of their lesson plans, allows students to attend classes from any location of their choice, can be recorded for further reference, more affordable as compared to physical learning, improves students attendance, is the good method forcreating a learning environment. An unsimilar study by JuliaYu-Fong Chang et al revealed that dental college students preferred online teaching as compared to physical classroom teaching 12 . This difference may be due to well-trained teachers and the availability of resources in Taiwan for online teaching.
Among samples who preferred online teaching mostly said an inability to focus on the screen for a longperiod, the greater chance for students to easily distracted by social or other sites, bigger challenge of online classes is internet connectivity, feeling of lowliness because students miss their pears, required teachers to have online teaching training and health hazard due to increase screen time, statements on inability to focus, internet connectivity and sense of isolation.In a local study from Lahore Pakistan, school and university students had a lot of problems during online classes. A total of 88% of students had no internet facility, 65% of students were not satis ed with the online teaching method and 85% of students had eyesight issues 7 .Higher Education Commission (HEC) Pakistan stated that teachers and students faced a lot of problems with online learning. Most of the students had noaccess to Wi-Fi or computers 13 .Another similar local study showed that online teaching had an improper study environment, insu cient online study material, no access or slow internet speed, and load shedding problems 14 A study was conducted in private universities of Pakistan, results regarding online teaching were similar to us stating that lack of internet facility, load shedding, nancial issues, ear pain due to prolonged use of hand-free/Blue-tooth and unreliable results in assessments were the major problems faced by the students 15 .
Among students who adopted physical teaching; all agreed that physical education provides a healthy environment to students for learning, build the character of a child, get the chance tointeract with their subject teacher, learn a lot from the presence of their peers, clears the concepts of the students by interacting with their teachers, motivate the students to attend their respective institutions, reward associated with physical education, it makes the carrier of the students, provides a sense of competition among students, taking too much of the students time, and is expensive as compared to online teaching.
Our results are consistent with an Indian study that showed that the physicalclassroom teaching method is better in understanding, convenience for attending class, notes-taking, visibility, audibility, raising queries 16 .A study from the European country proposed that a lack of proper equipment at home, a lack of proper training for information technology use were among the highest-ranked di culties during online teaching 11 .
We concluded that the majority of our students like and favor the physical teaching method as compared to the online teaching method.
